Answer:

It's the 2nd one

Step-by-step explanation:

To find the number of yellow marbles, you would do the number of blue marbles plus 6 marbles.

So in this case, let's say n was equal to the number of blue balls, the equation would be n+(n+6)=24.

What if n was equal to the number of yellow balls. The equation would be n+(n-6)=24.

Hope this made sense, let me know if you are still confused.

How do you graph y-2=1/2 (x+6)

jeyben [28]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

Convert the given equation to the slope-intercept form:

$y-2=\dfrac{1}{2}(x+6)$ use distributive property a(b + c) = ab + ac

$y-2=\dfrac{1}{2}x+3$ add 2 to both sides

$y=\dfrac{1}{2}x+5$

It is a linear function. We only need two points to plot the graph.

The first point we have from point-slope form → x₁ = -6, y₁ = 2 → (-6, 2).

The second point we have from slope-intercept form → b = 5 → (0, 5)

The probability of a train arriving on time and leaving on time is 0.8. The probability that the train arrives on time and leave

kkurt [141]

Answer:

0.9524

Step-by-step explanation:

Note enough information is given in this problem. I will do a similar problem like this. The problem is:

The Probability of a train arriving on time and leaving on time is 0.8.The probability of the same train arriving on time is 0.84. The probability of the same train leaving on time is 0.86.Given the train arrived on time, what is the probability it will leave on time?

Solution:

This is conditional probability.

Given:
